100
This is what makes atoms become negative.
What is when they gain electrons.
100
This is an imbalance of positive and negative charges causing a build up of charge.
What is static electricity.
100
Charges that are the same do this.
What is repels.
100
This is the Law of Conservation of Charge
What is charge can not be created nor destroyed just transferred so in a closed system total charge remains constant.
100
This is why atoms are electrically neutral.
What is electrons and protons have equal but opposite charges.
200
This is what makes atoms become positive.
What is losing electrons.
200
This type of charging requires two neutral objects to be rubbed together allowing the transfer of electrons.
What is friction.
200
This is what happens with oppositely charge objects.
What is they will attract each other.
200
Coulombs Law states that the electric force is directly proportional to this.
What is the product of the charge.
200
This is represented by the letter"q".
What is the charge of an object.
300
These materials hold tight to their electrons.
What are insulators.
300
This type of charging occurs when a charged object touches an uncharged object and transfers part of its charge.
What is conduction.
300
When hair is charged with a balloon it loses electrons. The hairs then stand apart from each other because of this.
What is all the hairs are positively charged so they repel each other.
300
Coulomb's Law states that the electric force between to charges is inversely proportional to this.
What is distance between the two charges
300
These are the units of charge.
What is a Coulomb(C).
400
These materials hold on to their electrons loosely.
What are conductors.
400
This type of charging occurs when a charged object is brought close to an uncharged object which is then grounded.
What is charging by induction
400
This is the term that describes the slight shift of electrons in an insulator in the presence of another charged object.
What is polarization.
400
When the distance between two charged particles is tripled, this happens to the electric force.
What is it's force is reduced to 1/9th as strong.
400

These types of forces act from a distance.

What is a non-contact (field) force.

500
The purpose of the triboelectric series.
What is ranking materials in order of their ability to hold or give up electrons.
500
A positive object is brought towards a neutral conductor which is then grounded.This is what happens when grounded.
What is electrons go into the conductor making it negatively charged.
500
This is the process that allows balloons to stick to walls.
What is bringing the charged balloon near the wall which pushes electrons away by induction leaving positive charges to attract the negative balloon.
500
These are two differences between gravitational and electric fields.
What is gravitational force is weak and electric force is strong, gravitational force is attractive electric force is attractive and repulsive.
500
These represent the direction and strength of an electric field.
What is electric field lines.
